Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 4 generators on 28 points:

(2,3)(5,6,10,7,8,11,9,12)(13,14,18,20,17,22,16,21)(15,19,25,28,23,27,24,26);(1,2,4,3)(5,7,10,11,8,12,9,6)(13,15,16,24,17,23,18,25)(14,19,21,26,22,27,20,28);(6,7)(9,10)(11,12)(14,20)(15,23)(16,18)(19,26)(21,22)(27,28);(1,3,4,2)(6,11)(7,12)(15,23)(19,27)(24,25)(26,28)
